Title: Method of forming contact via by hard mask
Inventor: CHEN CHAO-CHEN
IPC: H01L21/768
Filed: 1998-01-08
Granted: 1999-06-01
Abstract: In a conventional process for forming a contact via, a photoresist pattern is used directly as the mask for performing etching. Along with the miniaturization of the component dimensions, the thickness of the photoresist must be reduced to adapt to the ever increasing demand on the allowable process window in the photolithography process. However, the decrease in the thickness of photoresist causes a reduction in the anti-etching capacity thereof thereby causing the photoresist to be depleted prior to the completion of the formation of the via. In order to rectify the problem, a TiN hard mask process is proposed. The process comprises transferring the pattern on the photoresist to a TiN layer by a primary etching; then using the TiN layer having a better anti-etching capability as a mask for performing the subsequent etching process thereby forming a via with reduced dimensions. However, this hard mask process will cause new problems such as a reduction in the etching speed and unevenness in the sidewalls of the via due to the fact that the TiN layer contains no carbon element. Therefor, the present invention proposes an improved hard mask process which uses an MOCVD technique to purposely form a carbon-containing TiNxCy layer as the hard mask thereby providing the carbon element to promote the etching process of the via, and consequently increasing the etching speed and promoting the production of a contact via with smoother sidewalls.

Granted: 2003-08-21
Abstract: Disclosed is a simplified of manufacturing liquid crystal displays. A gate wire is formed on the substrate. A gate insulating layer, a semiconductor layer, and a ohmic contact layer are sequentially deposited, and a photoresist layer is coated thereon. The photoresist layer is exposed to light through a mask and developed to form a photoresist pattern. At this time, the first portion of the photoresist pattern which is located between the source electrode and the drain electrode is thinner than the second portion which is located on the data wire, and the photoresist layer are wholly removed on the third portion except for the first and second portions. The thin portion is made by controlling the amount of illuminating light or by a reflow process, and the controlling the light amount is done by using a mask which has a slit, a small pattern smaller than the resolution of the exposure device, or a partially transparent layer. Next, the exposed portions of conductor layers are removed by wet of dry etching, thereby the ohmic contact layer thereunder is exposed. Then the exposed ohmic contact layer and the semiconductor layer thereunder are removed by dry etching along with the first portion of the photoresist layer. The source/drain electrodes are separated by removing the portion of the conductor layer at the channel and the ohmic contact layer pattern thereunder to complete a data wire. Then, a passivation layer, a pixel electrode, a redundant gate pad, and a redundant data pad are formed. Here, the channel portion may be formed with one shape selected from a group of shapes including a linear, a square, an open-ring, or a semicircular shape and the mask has first to third parts corresponding to the first to the third portions and a fourth part having transmittance larger than that of the first part and smaller than that of the third part and located between the first and the third parts.

Title: Quadriphase spreading codes in code division multiple access communications
Inventor: POPOVIC BRANISLAV M
IPC: H04J13/18
Filed: 1999-06-21
Granted: 2001-08-01
Abstract: Optimal code sequences are generated for use in spreading and de-spreading functions in a code division multiple access (CDMA) communications system. In particular, a family of quadriphase spreading codes is employed that provides a maximal number of spreading codes to achieve a high capacity in the CDMA communications system while at the same time having a minimal peak cross-correlation between any two spreading codes within that family to ensure cross-correlation interference is kept at or below acceptable levels. That optimal quadriphase spreading code family is the S(2) family of four phase code sequences of length L=2<SP>m-1</SP>, where m is an integer greater than or equal to 5. The size of the S(2) family of quaternary spreading codes is (L+2)(L+1)<SP>2</SP>, and the maximum cross-correlation is 1+4(L+1)<SP>1/2</SP>. The spreading codes are preferably allocated to base stations using specific code subsets of the S(2) family having the same cross-correlation properties of the S(0) and/or S(1) family of codes. Spreading codes are advantageously extended by one or more code symbols as necessary or otherwise desirable. For example, to support variable transmission rate services, it is desirable to employ spreading codes whose length may be expressed as an integer multiple of each spreading factor in the mobile communications system. Since individual spreading codes have a length of 2<SP>m</SP>-1, one code symbol is added to the generated spreading code.
